I can get that we may have created something (quark-gluon plasma) at 4 trillion degrees Celsius that is hotter than a supernova, but…
How could we have created the coldest thing ever, at 100pK (less than 1 K), and that there is nothing colder? Might a single atom in deep space not have less energy? Apparently some nebula is the coldest thing out there.

Few humans went to space for experiments (mainly in International Space Station) with limited amounts of equipment
